摘要: 目的 使用前瞻性城乡流行病学(PURE)研究的数据,探索在中国人群中久坐时间与全因死亡和心血管疾病(CVD)的关系。方法 依托前瞻性城乡流行病学中国地区(PURE-China)队列研究,自 2005—2009 年通过标准化问卷及体格检查对受试者进行基线调查,并随访至2022年8月31日,主要研究终点为全因死亡和CVD(非致死性心肌梗死、卒中或心力衰竭)。通过多因素Cox共享脆弱模型分析中国人群中久坐时间与全因死亡及CVD风险的关联,并比较在不同性别、年龄和城乡中的关联差异。结果 本研究共招募 47 931名参与者,最终43 367名纳入分析。平均随访(11.9±3.0)年,共2 277例参与者发生全因死亡事件,3 551例参与者发生CVD。多因素Cox共享脆弱模型表明,相较于久坐小于4 h的人群,久坐时间6~8 h全因死亡风险增加23%(HR=1.23,95% CI:1.06~1.44),CVD风险增加18%(HR=1.18,95% CI:1.04~1.33);久坐时间8 h以上全因死亡风险增加50%(HR=1.50,95% CI:1.16~1.94),CVD风险增加44%(HR=1.44,95% CI:1.16~1.79)。在男性和年龄50岁以上人群中这种关联更加明显。结论 中国人群中久坐与全因死亡及心血管疾病的风险增加有关,尤其是久坐6 h及以上。减少久坐时间和增加体力活动可能是减轻心血管疾病负担和过早死亡的重要策略。

Abstract: Objective To explore potential association between sedentary time and the risk of all-cause mortality and cardiovascular disease (CVD) in Chinese population using data from the Prospective Urban Rural Epidemiology (PURE-China) cohort study. Methods Baseline data were collected, from 2022 standardized questionnaires and physical examinations, with follow-up until August 31, 2022. The primary endpoints were all-cause mortality and cardiovascular events (non-fatal myocardial infarction, stroke or heart failure). Multivariable Cox shared frailty model was used to analyze the association between sedentary time and the risks of all-cause mortality and CVD in the target population, and to compare differences across subgroups based on gender, age and geographic location. Results A total of 47 931 participants were recruited, and 43 367 were included in the final analysis. Over a median follow-up of 11.9±3.0 years, 2 277 participants experienced all-cause mortality, 3 551 experienced cardiovascular events. The Cox model indicated that, compared to individuals with less than 4 h of sedentary time per day, those with 6-8 h had a 23% increased in risk of all-cause mortality (HR=1.23, 95% CI: 1.06-1.44) and an 18% increased risk of CVD (HR=1.18, 95% CI: 1.04-1.33). For individuals with more than 8 h of sedentary time, the risk increased by 50% for all-cause mortality (HR=1.50, 95% CI: 1.16-1.94) and 44% for CVD(HR=1.44, 95% CI: 1.16-1.79). These associations were more pronounced in men and individuals aged 50 years and older. Conclusions Sedentary behavior is associated with an increased risk of all-cause mortality and cardiovascular disease in Chinese population, especially in the population with sedentary time of 6 hrs or more per day. Reducing sedentary time and increasing physical activity is an important strategy to mitigate the disease burden of cardiovascular disease and premature death.
